Saw Blade Stability And Collet System Mechanism

摘要

A surgical system for cutting tissue of a patient includes an outer housing and a reciprocating assembly structurally configured to carry a cutting tool in a reciprocating motion. An actuator knob is manually accessible to the user and may be fixed axially to the outer housing. The reciprocating assembly may reciprocate relative to the actuator knob. The actuator knob may be configured for rotational movement between a lock position and an unlock position. The system may also include a locking mechanism configured to retain a cutting tool within the reciprocating assembly. The locking mechanism may be responsive to movement of the actuator knob to maintain the tool within the output shaft when the actuator knob is in the lock position and permit removal of the tool when the actuator knob is in the unlock position. Surgical cutting tools, such as blades include thickness enhancing features.

主权项

1. A surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw, the cutting blade comprising:
a distal portion comprising a plurality of cutting teeth; a proximal portion disposed opposite the distal portion, the proximal portion being shaped to attach to the surgical saw and being formed of a material having an upper surface and an opposing lower surface, the material having a first thickness; and intermittent thickness enhancing features on the proximal portion, the thickness enhancing features having a high point offset from the upper surface and a low point offset from the lower surface of the material, the distance between the high point and low point forming a second thickness greater than the first thickness.
